been having problems with a lot of white smoke at first startup.It goes away as i drive down the road or should say when it warms up.I was wondering if you guys up north experience this in the really cold weather with the diesels.

is it clear white smoke? the truck is turbo so it could be just from that all turbo cars or trucks put out white clear smoke...

yeah if it goes away then should be ok.. just take it to your dealer or a shop and ask them also has the truck gottin a tune up?

I would take it in to have the valves adjusted. It's very, very important to have this service done every 50,000 miles on the isuzu diesel. I had it done at 50000, my valves were way out of adjustment. I noticed improved power and mpg, and my engine was much quieter after this service.

My npr is a 2003, our trucks should have the same 4.7 inline 4.
